Description
Technical field
The present invention relates to the assay device of test compacting effect, a kind of Experimental Study On Mechanical Properties laterally tamping effect for testing fragmented rock body.
Background technology
Coal, as the main support energy of China, along with the fast development of Chinese national economy, is positioned at the electric power in coal downstream, iron and steel, railway etc.
The demand of coal is strengthened by industry year by year, causes coal mining speed in recent years to be accelerated, along with the prolongation of the pit mining time limit with adopt deep extension, and one
Criticizing resource exhaustion mine and step into residual adopting the stage, part mine has been enter into phase of decline, and the even closing well having is changed the line of production." old and feeble " phenomenon in colliery is
Becoming the common problem of Resources-based Enterprises, for there being the mine of decline tendency to also result in enough attention, have in the face of with traditional in most of mining areas
The problem of " three times " (under building, under railway, under water body) pressure coal that technology cannot be exploited.On the other hand, in the mistake of China's fast industrialization
Cheng Zhong, creates substantial amounts of solid waste every year, and these garbages occupy cultivated land, pollute environment.Therefore consider to utilize solid waste to replace coal
Charcoal realizes lasting exploit, and this is seminar of China Mining University scientific achievement in recent years, so and solve " three times " pressure coal scale exploitation
Problem, solves again the storage problem of ground solid waste, is truly realized lasting exploit.When carrying out filling mining, utilize production technique handle
Goaf is also utilized filler to carry out filling by coal extraction, and the density of such filler is critically important factor, and it directly influences rock stratum
Across falling, the filling effect such as subsidence.The present invention intends when carrying out filling mining, and the compacting effect of filler carries out the assay device of test analysis.
Summary of the invention
Technical problem: it is an object of the invention to provide a kind of compact conformation, the most laterally tamp pilot system.
Technical scheme: the present invention relates to a kind of compact conformation, test fragmented rock body laterally tamps pilot system safely and efficiently.Fragmented rock body laterally rams
Real pilot system is mainly loaded transmission system, bearing system and test system three part and constitutes by horizontal force.Described horizontal force loading system is by upper company
Connection device, rocking bar, connecting pin, fixed frame, connecting rod and horizontal pressure head are constituted；Described bearing system is by inwall, column, sleeve and outer wall structure
Become；Described measurement system is made up of spring and pressure cell, and pressure cell can connecting data handling system carries out Data acquisition and issuance in addition.Solution of the present invention
Determine the test of lateral compacting effect of fragmented rock body and analysis, it is possible to analyze different materials compacting effect test under various horizontal force actions, be
System simple in construction, easily realizes.
Beneficial effect: the present invention, for testing the relations problems between fractured rock stress under lateral load effect and deformation, solves lateral rammer
The real relation analysis between lateral compacting power and the deformation tested in difficulty, engineering.Content of both can testing: one is to be come by pressure cell
Test power within fragmented rock body, two is stress and the deformation being measured fractured rock by ruler.Whole system compact and reasonable, easy to operate,
Safe and efficient, small investment, laterally tamps measure of merit to the material in coal filling mining and has wide applicability, for other mine engineering
There is reference.
Accompanying drawing explanation
Accompanying drawing is that the present invention tests fragmented rock body and laterally tamps the assay device structural representation of effect.
In figure: the upper attachment means of 1-, 2-rocking bar, 3-connecting pin, 4-fixed frame, 5-connecting rod, 6-side pressure head, 7-inwall, 8-sleeve, 9-column,
10-outer wall, 11-crushes rock sample, 12-spring, 13-pressure cell.
Detailed description of the invention
Below in conjunction with the accompanying drawings one embodiment of the present of invention is further described:
As it can be seen, the present invention laterally tamps the assay device of effect for testing fragmented rock body, mainly loaded transmission system, carrying system by horizontal force
System and test system three part are constituted.Described horizontal force loading system is by upper attachment means 1, rocking bar 2, connecting pin 3, connecting rod 5 and side pressure 6
Constitute；Described bearing system is made up of inwall 7, column 9, sleeve 8 and outer wall 10, and its inwall 7 is by the identical prose style free from parallelism structure of some block sizes
Become；Described measurement system is made up of spring 12 and pressure cell 13, pressure cell 13 can with external data processing system with carry out pressure collection and
Analyze.
During work, start drive system, by driving upper attachment means 1 to move down, by the rocking bar 2 in left side, fixed frame 4, connecting pin 3,
Connecting rod 5, is converted to lateral driving force vertical driving force, and driving side pressure head 6 moves right；Broken rock sample 11 is promoted to carry out to the right filling mould
Intend, gradually become closely knit from loose condition (of surface).During side pressure 6 carries out that repeating moves right and carries out tamping the broken rock sample 11 of filling,
Constantly should add broken rock sample 11 toward assay device is internal, the density of such guarantee filling improves constantly.Along with stowing operation, examination
The inwall 7 of experiment device can produce the most mobile, thus the spring 12 in sleeve 8 can produce slowly deformation, and column 9 can make spring 12 is spacing
It can not move radially.During filling, the stress shape within broken rock sample 11 can be gathered by the harvester that pressure cell 13 is external
State, it is also possible to analyze its stress and deformation by spring 12 deflection between inwall 7 and outer wall 10.So carry out repeated tests, finally
Solve the problem testing lateral filling compacting effect.
